In this architecture, I divide the art gallery into 4 levels, which are based on these two concepts respectively---- warmth and penetration. Up-ground part has two floors, which is related to warmth for the word "chicken".The ground floor is the exhibition place for publics. Meanwhile first floor is the studio for MUECK. With the shape of up-grounda, it looks like a roost which can give chooks a shelter and warm. Besides, under-ground part has two floors using as studio place for BANKSY. Even though under-ground part likes a combination of cages, the vitality of BANKSY's scrawl can break this voodoo and energize the art gallery, which is the penetration I mean.
